.SH "DESCRIPTION"
.PP
\fBTspi_TPM_CheckMaintenancePubKey\fR
checks the public maintenance key. If \fIhMaintenanceKey\fR
is NULL, then \fIpValidationData\fR must not be NULL; the caller has to
proof the digest on its own. If \fIhMaintenanceKey\fR is not NULL, then
\fIpValidationData\fR must be NULL; the TSS service provider proofs the
digest got internally from the TPM. The key information required for
proofing the public maintenance key must be set in the key object by
Tspi_SetAttribData before this method is called. \fBThis function is
not yet implemented\fR.
.SH "PARAMETERS"
.PP
.SS hTPM
Handle of the TPM object
.PP
.SS hMaintenanceKey
Handle of the maintenance key object
.PP
.SS pValidationData
Validation data structure.
[IN] Provide externalData information required to compute the signature.
[OUT] On successful completion of the ocmmand, the structure provides a
buffer containing the validation data and a buffer containing the data
the validation data was computed from.

.SH "RETURN CODES"
.PP
\fBTspi_TPM_CheckMaintenancePubKey\fR returns TSS_SUCCESS on success,
otherwise one of the following values are returned:
.TP
.SM TSS_E_INVALID_HANDLE
\fIhTPM\fR is not a valid handle.
.TP
.SM TSS_E_INTERNAL_ERROR
An internal SW error has been detected.
.TP
.SM TSS_E_BAD_PARAMETER
One or more of the parameters is incorrect.
.TP
.SM TSS_E_NOTIMPL
The command is not implemented.
